Which parts can the nail plate be divided into?

The correct response identifies the primary components of the nail plate itself, which are instrumental in both anatomy and functionality. The nail plate can be divided into three distinct parts: the nail root, which is the embedded portion beneath the skin; the nail body, which is the visible part of the nail; and the free edge, which extends beyond the fingertip and is the part that is often trimmed.

Understanding these components is essential, as each plays a critical role in the health and growth of the nail. The nail root is where the nail grows from, the body provides protection and contributes to the appearance of the nail, and the free edge helps prevent damage to the underlying skin of the fingertip. Recognizing these divisions allows for better comprehension of nail care and potential issues that may arise.

The other options present different parts of the nail structure but do not accurately reflect the division of the nail plate itself. They contain components related to the overall anatomy or support structures of the nail but do not specify the parts as they are classified purely within the nail plate.
